Application filed December 14, 1923. "Serial No. 880,723.

To all 107L071), it may concern:

Be it known that I, KVALTER KDKEN, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Hair Dressers and Barbers Chairs, of which the followingis a full, clear, and exact description, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to adjustable chairs of the kind that are used byharbors, hair dressers and other specialists for support ing a person onwhom the specialist is operating, and particularly chairs of the kindthat are equipped with a swinging apron and a swinging foot rest that isadapted to be turned into different positions with relation to theapron.

The main object of my present invention is to provide a chair thatembodies some of the good features and characteristics of the chairdescribed in my pending application for patent Serial No. 680,722, filedDec. 1 1-, 1923, which is equipped with a novel operating andcontrolling mechanism for the foot rest. v

Another object is to improvethe operation and simplify the constructionof the mechanism that is used in hair dressers and barber's chairs andthe like for clamping and releasing the recliningbar that holds theback, seat and apron of the chair in adjusted position.

Fi 'ure 1 of the drawings is a side elevationa view oi a chair embodyingmy invention, showing the back of the chair arranged in its uprightposition.

Figure 2 is a vertical transverse sectional View, taken through the stemof the chair, illustrating the operating shaft that controls thereclining bar clamp.

Figure 3 is a side elevational view. illustrating the back of the chairin its fully reclined position; and

Figure 4: is a top plan view of the parts shown in Figure2.

Referring to the drawings, which illustrate the preferred form of myinvention, A designates the back, B designates the seat, C designatesthe apron and D designates-the foot rest,.-the back, seat and apron -bein combined in --.su'ch a manner that they. wil% movein unison intolongitudinal alignment with each othe when the back mesa downwardly intoits fully reclined position, shown in Figureii, and will move into aposition at substantially right angles "to each other when the back isswung upwardly into its upright position, shown in Figure 1. said partsare carried by a frame E which may either be a stationary frame or aframe that can be, raised and lowered, the frame E 01, the chair hereinillustrated being car- Tied by a spindle F that is mounted on a base G.The arms oi? the chair may either be adjustable or stationary and areherein illustrated as being rigidly connected to front and rearuprights1 and 2 on the frame E. The seat B is so arranged with relation to the"arms 1-1 that it will move forwardly and upwardly towards said armswhen the back A is swui'igdownwardly into its fully reclined positionand will move rearwardly and downwardly away from said arms when theback is moved into its upright position. In the form of my inventionherein illustrated the back A is rigidly "connecte'dto a pair oit levers3 that are pivotally connected 4 to the rear uprights 2 on the frame E,and the apronC is rigidly connected to a pair of levers 5 that arepivotally co'nnected at 6 to the front upriglits 1 on said frame. The:seat B is carried by two links 7, shown in broken lines in Figure 3,whose rear ends are pivotally connected at 8 to the lower ends of thelevers 3 and whose iront ends are pivotal-1y connected at 9 to thelevers 5 that carry the apron, thereby producing a chair in which theback, seat and apron will move simultaneously either into the positionshown in Figure 1 or into the position shown in Figure 3 when the back Ais swung on its pivots 4;.

The means that is used "for holding the back, seat and apron in adjustedposition consists of a conventional reclining bar I pivotal ly connectedat its front end to the apron C, and ,a reclining bar clamp embracingsaid reclining bar and designated as an entirety by the referencecharacter J, said clamp being composed of two spring-pressed jaws 10mounted. in such a manner that they can rock or turn from the positionshown in Figure v1 into the position dotted lines in Figure 8,;so as topermit the reclining bar to swing upwardly. One of the jaws 10 is acteduponby a spring llthat causes saidjaws to clamp and securel hold thereclining bar I, and an operating shaft turns.

K is provided for separating the jaws 10, so as to release the recliningbar when it is desired to change the adjustment of the back, seat andapron of the chair. The operating shaft K is arranged transverse-1yunder the seat of the chair-and is oscillatingly mounted in bearings 12on the spindle F, as shown in Figure 2, said shaft having ascrew-threaded portion 13 that cooperates with screw threads in one ofthe aws lO'to cause the shaft K to move endwise when it is rocked in onedirection,and thus cause an abutment or shoulder onsaid shaft to exertpressure on the outer jaw 10 in a direction to move saidouter jaw awayfrom the ibnner jaw, thereby releasing the reclining ar I.

The operating-shaft K is provided at each of its ends with a handle L,so as to enable said shaft to be operated fromeither side of the chair,and means is provided for nor? mally holding said operating shaft insuch a position that the reclining bar clamp J will be operative, or, inother words, will be in a condition to lock the reclining bar. Theholding means just referred to preferably consists of an arm 1 1 on theoperating shaft K arranged inside of the hollow spindle F of the chair,as shown inFigure 2, a cam'or inclined lug 15 on the inner side of saidspindle that co-operates with the'arm 14, and a coiled compressionspring 16 surrounding the operating shaft between a pin 17 thereon andone of thebearings 12 in which the shaft The spring 16 exerts endwisepressure on the shaft K when said shaft is turned in a direction tocause the arm 14: thereon to ride up onto the high part of the cam 15,thus frictionally holding the shaft K in such a position that thereclining bar clamp J will be operative. hen it is desired to change theadjustment ofthe parts of the chair the operator turns the shaft K in adirection to cause the arm 14 thereon to ride down off of the high pointof the'cam 15, this rotary movement of the-shaft K causing the outer jaw10 of the reclining bar clamp to be moved away from the inner jaw ofsaid clamp sufficiently to release the reclining bar I, whereupon theback, seat and apron of the chair can be moved to change the position ofsame. a I

The foot rest I), previously referred to, is pivotally mounted on theapron C and mechanism is provided for insuring said foot rest movingint-o a position wherein it forms an extension of the apron C when theback of the chair is arranged in its fully, reclined position, andmoving into aposition wherein it is disposed at substantially rightangles to the apronC when the back of the chair is swung upwardly intoits vertical position. Preferably the foot rest D is connected by offsetpivots '18 to the lower ends of the levers 5 which carry the apron C,and the mechanism that controls the position of said foot rest andcauses it to move relatively to the apron when the parts of the chairare adjusted from one position intoa different position consists of acam M connected to the front end portion of the reclining bar I, av

rockable member vO pivotally mounted on the underside'of the apron C anda link P that connects said rockable member to an angularly-disposed arm19 on the foot rest D, the rockable member-preferably consisting ofabell crank lever having'one of its arms pivotally connected to the linkP and having its other arm equipped with a roller 20 that is arranged inengagement with the cam M.

WVhen the back of the chair is swung downwardly into its fully reclinedposition the reclining bar I moves forwardly and up wardly, and as saidreclining bar approaches the end of its forward stroke, the roller 2-0on the rockable member 0 passes from the convexed portion w of the cam Monto the straight vertical face y of said cam, thereby causing themember 0 to rock-in a direction to exert a pull on the link P, whichaction insures the-foot rest being disposed in longitudinal alignmentwith the apron C at the time the back of the chair reaches its fullyreclined position, as shown in Figure 3 lVhen the back of the chair isswung up wardly from the position shown in Figure 3 into the positionshown in Figure 1, the en? gagement of the roller 20 on the rockablemember O with the straight vertical surface 3 of the cam M, during thefirst portion of the downward movement of the apron causes the member 0to exert a thrust on the link P, thereby positively turning the footrest D into a right-angular position with relation to the apron.Thereafter, during the remainder of the downward movement of the apron,the foot rest is held in a positionat substantially right angles to theapron by the engagement of the roller 20 on the member O with theconvexed surface m of the cam M. Accordingly, in my improved chair thereis no possibility of the foot rest D remaining in longitudinal alignmentwith the apron C when the apron swings downwardly, because means isprovided for positively turning the foot rest into, a'position at rightangles to the apron during the first part of the downward movement ofthe apron and for maintaining the foot rest in said position while theapron continues to move downwardly. The foot rest D is preferably provided adjacent its front edge with casters or rollers 21 that bear uponthe floor when the back of the chair is in its upright position.

Y I Having thus described my invention, what I claim as new and desireto secure by Letters Patent isi I v A chair provided with a swingingapron, a foot rest carried by the aproma rockable member on the apron, apositive connection between said rockable member and foot rest fortransmitting movement from one of said parts to the other, a recliningbar connected with the apron, and a cam on said reclining bar arrangedso as to enand actuate said rockable member when the apron moves :tromone position to another position.

2. A chair provided with a swinging apron that is adapted to be raisedand lowered, a swinging foot rest combined with the apron, a rockablemember on the apron, means :tor positively connecting said rockablemember with the foot rest, a reclining bar connected with the apron, anda cam member 011 said reclining bar arranged so as to co-operate withsaid rockable member to change the angular relationship between the footrest and apron when the ap-ronvis 'aised and to re-establish the normalrelationship between said apron and foot restwhen the apron is lowered.

3. A chair provided with an adjustable back and an adjustable apron, aswinging toot rest combined with the apron, a rec1ining bar connectedwith the apron, a cam carried by said reclining bar, and a rockablemember on the apron operatively connected with the foot rest andarranged so that it will co-operate with said cam to turn the foot restinto a position at right angles to the apron and maintain the foot restin said position during the movement of the apron from its horizontalposition into its vertical position. a

4. A chair provided with an adjustable back and an adjustable apron, aswinging foot rest combined with the apron, a reclining bar pivotallyconnected to the apron, a cam on said bar, a rockable member on theapron arranged so as to be actuated by said cam during the movement ofthe apron from one position to the other, and means operated by saidrockable member for positively turning the foot rest into and out of anangular position with relation to the apron during the operation ofchanging the adjustment of the back and a-pron of the chair.

5. A chair provided with a swinging back and a swinging apron, apivotally mounted foot rest carried by said apron and provided with arigid arm, a bell crank lever on said apron, a link pivotally connectedto said lever and to the arm of the foot rest, a roller on said bellcrank lever, a reclining bar pivotally connected to the apron, a cam onsaid reclining bar adapted to co-operate with said roller and providedwith one surface that causes the bell crank to turn the foot rest into aright-angular position with relation to the apron during the downwardmovement of the apron, and an independent surface on said cam-that cooperates with said bell crank to maintain the foot rest in saidposition.
